Twitter hasn’t released a native app for the BlackBerry PlayBook. They have recently improved the mobile-friendly web app that looks…good. But for those of us who want a native app that can deliver more features and customization while we surf Twitter, TweetBook might just be what you’re looking for.

One of the main features of TweetBook is the ability to switch between multiple accounts. This is must-have for users who have a personal account and also a business account where they Tweet about business discounts, deals, and subjects related to what goods/services their business provides. No one wants to deal with constantly loggging off and back on. TweetBook also offers on screen notifications, so you are notified if a mention or direct message is directed towards you or your business account – something that currently can’t be done via the mobile-friendly version. Other native features include:

- Threaded Messaging (view you messages in one screen like txt messages on a smartphone)

- Camera Support (snap pics and upload directly to a tweet)

- Search Support

- Works in Portrait and Landscape Mode

I’ve said it before and I’ll say it again, there’s nothing like free publicity by marketing your business using Social Media. With TweetBook for BlackBerry, you don’t have to go out and buy an iPad to get a native-like mobile Twitter experience. So if you’re one of the brave-new early adopters of the PlayBook, check out the TweetBook app ($4.99 in BlackBerry AppWorld) and let us know what you think in the comments section.
